%X the vickers micro-hardness of this alloy was unusually dependent on the heat treatment from 300 to 634k, inferring important micro-structural changes and the presence of amorphous grains before its phase transition. once the alloy is crystallized, the micro-hardness is characteristic of a brittle alloy, the main problem of these alloys. within the amorphous state, other properties like free-volume, magnetic states and fe-fe distances were followed by pals and ms, respectively, to analyze those micro-structural changes, thermally induced, which are of paramount interest to understand their brittleness problem.
